15. Option 5: Cruising the Mediterranean on the Alfa Nero.

Pros of the holiday include waking up in a different place every day, being able to park up and take long walks of the beach and privacy whilst on board. The main con to this holiday? It will set you back over one million dollars a week in peak season. Picture: Beyonce.com
